Ingredients Method Notes

Ingredients
  

  • 3 overripe bananas (about 1 1/2 cups mashed)
  • 1/2 cup unsalted butter, melted
  • 3/4 cup granulated sugar
  • 1/4 cup packed light brown sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/2 cup buttermilk
  • 2 cups all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 8 oz cream cheese, softened
  • 1/4 cup unsalted butter, softened
  • 2 cups powdered sugar
  • 1 tsp vanilla extract

Method
 

  1. In a large bowl, mash the bananas with a fork, then whisk in the melted butter, sugars, eggs, vanilla, and buttermilk until combined.
  2. Add the flour, baking soda, and salt. Stir just until no dry flour remains.
  3. Pour into a greased 9 x 13 inch pan and bake at 350°F for 25 to 30 minutes, until a toothpick comes out clean. Cool completely.
  4. Beat the cream cheese, butter, and vanilla until smooth, then beat in the powdered sugar until fluffy. Spread over the cooled cake, slice, and serve.

Notes

Use bananas that are heavily spotted for the deepest flavor. The cake can be baked a day ahead; store it unfrosted at room temperature, then frost before serving. If your bananas are small, use 4 to reach 1 1/2 cups mashed.
